-
(2004)Heat capacity (CV) and entropy (S) as a function of temperature were calculated for phases in the CaO-Al2O3 system from vibrational spectra using a quasi-harmonic model. Calculated values of CV at 298 K for the calcium ...
-
(2002)Sulfur and silicon are among the expected alloying light elements in planetary liquid iron cores. Structural properties of Fe-27 wt % S and Fe-17 wt % Si liquid alloys at high pressure and high temperature (0-5 GPa/1400-2300 ...

PHYSICAL PROPERTIES OF NEAR-EARTH ASTEROIDS FROM THERMAL INFRARED OBSERVATIONS AND THERMAL MODELING (2002)We review the physical principles on which asteroid thermal models are based and their application in the derivation of asteroid sizes and albedos. In particular, the use of simple thermal models to derive reliable diameters ...
-
(2001)Variations of physical properties of rocks of a thick sedimentary layer are analysed as functions of the lithogenesis temperature. The maximum depth of the sedimentary basin was establish as a thermal flow function. ...
-
(1996)The physical significance of "earthquake quanta" is discussed in the perspective of a proposed concept "seismon." It is pointed out that the physical significance of earthquake quanta may be understood in the way similar ...
-
(2000)Marbles as building stones as well as in their natural environments show complex weathering phenomena. The most important damage scenario is based on the highly anisotropic thermal expansion coefficient α of calcite, i.e. ...
-
(1998)Abstraet--Cu-doped alumina-pillared montmorillonite samples have been prepared and characterized with X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), electron spin resonance (ESR) and in- ductive coupled plasma ...
-
(1987)The peculiarities of weathering processes involving duration, slow change of ambient conditions, isothermality as well as proceeding in open systems permit to study these processes in a steady-state approach (, where Ci ...
-
(2001)Magnetite gabbro occurs in the central part of the layered intrusion of the western Pansky Tundra as layers and lenticular bodies from 20 to 100 m thick and from hundreds of meters to 10 km long. They show fine-grained ...
-
(2004)Alvinella pompejana is a polychaetous annelid that inhabits narrow tubes along the walls of high-temperature hydrothermal vent chimneys. The worm hosts a rich community of epibiotic bacteria that coats its dorsal surface. ...
-
(2004)A method is proposed for the physicochemical computer simulation of rock-water systems that can be used in predicting the changes that take place in the composition of fresh water in the course of hydrogeochemical processes. ...
-
(2003)Processes of heat and mass exchange at core-mantle boundary determine operation of thermochemical machine of the Earth and global geodynamics of the Earth. At the core-mantle boundary, thermochemical plumes are formed which ...
-
(2003)Various geothermometers were used to determine the physicochemical conditions (temperature, pressure, and oxygen fugacity) of crystallization of Late Cenozoic volcanic rocks in the Lesser Caucasus. The first data are ...
-
(2002)Fluid inclusions in minerals from more than 22 Au-Hg deposits (Central Asia, Urals, East Sayan, Gorny Altai, northeastern Russia, Mongolia, etc.) have been examined by thermobarogeochemical methods (thermo- and cryometry, ...
-
(1987)Olivinite was developed in the emplacement front of clinopyroxenite and gabbro, and its thickness is directly proportional to the combined thickness of these clinopyroxene-bearing rocks. Oxidation of dunite olivine and the ...
-
(2004)The precipitation of a set of minerals by condensation of magmatic fluid is an immanent specific feature of subaerial and submarine basic magmatic systems evolving at various depths. The description of temperature zoning ...
-
(2003)The main physicochemical factors controlling the composition of natural aqueous solutions are as follows: (a) the ratio of the reacting masses of rock and water (R/W); (b) the composition of the rock, particularly, the ...
-
(1987)The authors present the results of an attempt to employ physicochemical computer modeling of contact-infiltration metasomatism by convex programming methods in order to establish the origin of nephrite vein No. 7 in the ...
